My friend Andrea has a cool husband in a cool urban art/activism group with a cool project going on...if I wasn't on an airplane on September 21, surely I would be trying to spruce up the parking space in front of both stores with some greenery! I quote Andrea about the project, below.

The goal of PARK(ing) Day is to:

1) inspire people to reconsider the way our streets are used;

2) generate meaningful dialog regarding the planning principles that continue to unsustainably privilege the automobile above other uses of public space,

3) and to put a big smile on your face!
Hey New Yorkers - check out this great map with confirmed park locations, and add your own! SF folk, here is your map, and I'm sure there are more for other towns.
